Petroleum Fluid Meters

Hedland petroleum fluid meters are designed to seamlessly integrate into hydraulic systems. Additionally, with a variety of end fittings and different material types, these meters can be used in a wide range of industrial processes requiring flow monitoring of petroleum fluid types. Standard meters provide an economical solution for operators needing a quick, visual indication of flow, without the use of additional electronics. Expansion options are available to allow integration into remote systems via electronic output.

Overview

The Hedland Flow Meter is a variable area (rotameter) instrument. A precision machined, sharp-edged Orifice is located within the piston assembly and forms an annular opening with the contoured metering cone. The piston assembly carries a cylindrical PPS/ ceramic magnet that is magnetically coupled to an external flow Indicator that moves precisely, in direct response to movement of the piston. A calibrated spring opposes flow in the forward direction. This spring decreases viscosity sensitivity and allows the flow meter to be used in any position, including inverted.

Benefits

No electronics needed to obtain a reading

Can be installed in any position / orientation without affecting accuracy

The most readable product in its class

Does not require special plumbing or accessories to stabilize turbulent flow

Magnetic coupling eliminates the need for mechanical linkages that wear, loosen and leak over the functional life of competitive meters

Parts, Accessories & Other Options

The MR flow transmitter further expands the Hedland variable area (rotameter) product offering by allowing flow rates and totals to be digitally displayed or transmitted via current or voltage output. The unit features non-contact sensor electronics, an electronic signal conditioning circuit and in-field compensation capabilities. Flow meter elements are enclosed within a NEMA 12 and 13 (IP 52/54) rated enclosure and is CE compliant. The large LCD display allows for extended viewing ranges and easier programming.

The Hedland Flow-Alert is a variable area flow meter (rotameter) that provides a local flow indication and electronic switches to automatically signal system operators or PLCs if flow rate is below, or above, system specifications. Flow meter elements are enclosed within a NEMA 12 and 13 (IP 52/54) rated enclosure. Users can order meters with one or two Micro or Reed Switches, in normally open or closed states.

Test kits enable Hedland variable area flow meters (rotameters) to provide additional system information and diagnostic capabilities. Standard flow meters are affixed with a pressure gauge and needle valve assembly, specifically designed to allow the operator to introduce a pressure load on the system. Various instruments within a system can be tested or verified against manufacturer specifications to ensure proper functionality. Instruments tested in this manner help promote fluid power safety by allowing operators to get a clear, visible indication of system health during operation, without the dangers of close contact with operating machinery.
